https://docs.emtronaustralia.com.au/engine-management/functions/nb-heater-control/index.htmlThe Narrow Band Oxygen Sensor heater can be controlled using either switched or PWM mode. The method of control is adjusted from the Config View, Function Setup menu. Switched Mode This is the most basic mode and switches the heater channel ON after the Post Start Lockout has finished. Same setup as below except Output Mode = Switched. (This mode is not recommended) Switched Mode (Table) From Config View -> Functions, select the required Channel, either Heater 1 and 2 and open. Select the Output Channel. In this example Sensor Heater 1 has been assigned to Auxiliary 4. Select Driver Type (Normally Low Side). Select Output Mode = Switched (Table). This puts the heater control in switched mode and allows a 3D table to control the switching conditions. NOTE: The Output Mode set to “Switched” has the same effect as “Switched (Table)”Hugoen-us
